DETAILED DESCRIPTION

Described embodiments provide techniques to generate display groups to display qualifying content instances from one or more objects that satisfy a search criteria based on an attribute of the qualifying content instances. The attribute used to determine how to display the qualifying content instances may indicate an attribute of the content instances themselves, such as their type, frequency, correlation to the search terms, etc. Additionally, the attribute may specify an annotation, so that the display group provides a visualization of tags representing qualifying content instances for qualifying content instances associated with the specified annotation. Further, tags visualized together in a display group may be from one or more objects.

FIG. 1 illustrates an embodiment of a content analytics system 2 to provide an operating environment to process search requests from clients (not shown) for objects 6 maintained in a repository 4. The objects 6 may comprise textual documents, multi-media content with textual metadata, a database, and other data. The content analytics system 2 includes a search index 8 providing a listing of the content, such as words and text, in the objects 6. The index 8 may provide entries for terms and content in the objects 6 and indicate the objects 6 that include that indexed content.

An object processor 10 includes an indexer 12 to crawl the objects 6 to perform the indexing to generate the index 8. The object processor 10 may further include annotators 14 to apply text analytics to the objects 6 to generate annotations 16 providing additional information on the content of the objects 6. Text analytics provides techniques to convert textual data into structured data by extracting information from the text, e.g., person names, addresses, etc. and classifying content into categories based on the text. The object processor 10 may further generate facets providing components of information gleaned from the objects 6, which can be populated with information from structured fields or the text of the objects 6. The annotator 14 may comply with the Unstructured Information Management Architecture (UIMA), and include such annotators as a language identification annotator to identify the language of each object 6; a linguistic analysis annotator to apply linguistic analysis to the objects 6; a dictionary lookup annotator to match words and synonyms from a dictionary with words in the content of the objects 6 and to associate keywords with user-defined facets; a named entity recognition annotator to extract person names, locations, and company names;

A search processor 18 receives search requests from the client (not shown) and may determine objects 6 having content instances that satisfy the query. The search processor 81 may use the index 8 and annotations 16 to determine qualifying content instances, i.e., words or text, in the objects 6 to render as tags in a visualization of a display group, such as a word cloud. The search processor 18 may generate display group information 20 providing information on display groups of tags to generate together that share a common criteria, facets or annotations. A display group identifies tags to be visually presented together as a group, such as in a same display region of a graphical user interface (GUI), word cloud, panel, box, etc. The search processor 18 may construct a search result page 22 to present display groups including tags representing qualifying content.

The display group information 20 includes display group definitions (FIG. 2), display group instances (FIG. 3), and information on tags (FIG. 4) generated by the object processor 10, the display group manager 24 or some other component of the content analytics system 2. A display group manager 24 may be used to update the display group information 20 by allowing the user to define display groups and provide definitions on how to display tags, such as in a word cloud.

The repository 4 may comprise one or more storage devices known in the art, such as interconnected hard disk drives (e.g., configured as a DASD, RAID, JBOD, etc.), solid state storage devices (e.g., EEPROM (Electrically Erasable Programmable Read-Only Memory), flash memory, flash disk, storage-class memory (SCM)), electronic memory, magnetic tape media, tape cartridges, etc. The components of the content analytics system 10, 18, and 24 may comprise software programs in a memory executed by a processor. In an alternative embodiment, some portion or all of the programs may be implemented in a hardware component, such as a dedicated integrated circuit, e.g., Application Specific Integrated Circuit (ASIC), expansion card, etc.

FIG. 2 illustrates an embodiment of a display group definition 50, including a definition name 52, an object grouping criteria 54 indicating a criteria used to define a group of one or more objects whose content instances will be visualized in the group 50; a specified attribute 56 that is used to determine which content instances will participate in the group for the objects identified in the object grouping criteria 54; and appearance rules 58 providing different appearance settings for different attribute 56 values. The object grouping criteria 54 may indicate that the display group is to be generated for only content instances for a single object or from a group of objects, such as one or more objects satisfying a search criteria, predefined number of objects satisfying the search criteria, a number of objects that would be listed on a search results page, etc. The attribute 56 used to vary the appearance of the tags may comprise a frequency of a qualifying content instance satisfying search criteria in the object, a correlation of the qualifying content instances to the search criteria; a degree to which the qualifying content instance makes the object different from content instances in other objects; a correlation of the qualifying content instance to an aggregation of search requests; and an extent to which the qualifying content instance comprises a proper name, address or other identifying information.

Further, the attribute 56 may indicate an annotation type or facet of the data that is used to discriminate among qualifying content instances to present in the display group 50. For instance, the specified attribute 56 may identify an annotation type so as to only include in the display group 50 qualifying content instances that are associated with the specified annotation type attribute. Examples of annotation types include a tone annotation indicating an author tone, sentiment (e.g., angry, sarcastic, humorous, tragic, etc.) of a context in which the qualifying content instances are used, such that the attribute values 58 used to vary the appearance settings comprise different tones of the context of the qualifying content instances, a frequency of a tone, or correlation of the tone to the search criteria; a noun phrase annotation identifying content instances used in forming noun phrases, where the attribute value 58 indicates a frequency of an occurrence of the qualifying content instances within noun phrases; a named entity annotation indicating qualifying content instances forming person names, organizations and locations, where the attribute values indicate a frequency of an occurrence of the named entity in the object; and a time based annotation indentifying qualifying content instances comprising time based information, wherein the attribute value indicates a chronological time of the qualifying content instance, and wherein the appearance settings indicate a display of the tag on a time line according to an ordering of the chronological times associated with the qualifying content instances. Other types of annotations may also be used to select qualifying content instances to visualize in the display group. Further, the attribute 56 may identify multiple annotations or attributes, to combine in the display group 50.

A user of the content analytics system 2 may utilize a GUI provided by the display group manager 22 to create one or more display group definitions 50 for different object grouping criteria 54 and attributes 56 to be applied to display search results in response to search requests from clients (not shown) with respect to the objects 6.

FIG. 3 illustrates an embodiment of a display group instance 70 comprising a particular instance of a display group formed according to one display group definition 50. A display group instance 70 includes an identifier 72 of the instance, a definition name 74 identifying a display group definition 50 from which the instance 70 was created, and one or more tags 76 representing qualifying content instances in object as selected according to the display group definition 74 for which the instance was created. The display group instances 70 maybe generated when processing search results returned for a search query.

FIG. 4 illustrates an embodiment of a tag 80, including a content instance 82, such as a text item; an object 84 including the content instance 82; an appearance attribute value 86 used to determine how the tag is to be displayed, and an appearance setting 88 indicating how the content instance 82 is to visually appear in the display group (e.g., word cloud), such as font size, color, font, boldness, etc. The appearance rules 58 may be used to determine the appearance setting 88 corresponding to the appearance attribute value 86 determined for the content instance. The appearance attribute value 86 may provide a value for the display attribute 56 for the display group for which the tag is being generated, such as a frequency of the content instance 82 in the object, a correlation of the content instance 82 to the search criteria, an annotation of the annotation type corresponding to the display attribute 56, etc.

FIGS. 5-8 illustrate embodiments of operations performed by components of the content analytics system 2, such as the object processor 10 and search processor 18 to process a search request to generate visualizations of display groups of tags. With respect to FIG. 5, upon the search processor 18 receiving (at block 100) a search request providing search criteria with respect to the objects 6 from a client (not shown), the search processor 18 determines (at block 102) from the index 8 the objects 6 having qualifying content instances that satisfy the search criteria. Qualifying content instances that satisfy the search criteria may comprise content that matches the search criteria, such as a word stem of the content matching a word stem of the search terms, and/or comprise content that is correlated to the search criteria, such as determined by using data mining and/or text mining techniques.

The search processor 18 determines (at block 104) an attribute value 86 of the qualifying content instances for the specified attribute 56, and may store this information in tags 80 created for the qualifying content instances. The search processor 18 determines (at block 106) appearance settings 88 for the qualifying content instances based on the determined attribute values 86, such that the appearance settings 88 may vary based on the determined attribute values 86. The search processor 18 may store this determined information in the tags 80 created for the qualifying content instances. The search processor 18 may generate (at block 110) with the rendering of the visualization of the tags in the display group links to information on the objects having the qualifying content instances visualized by the tags. The links may be to the object itself, or to a page of search results including the object having the qualifying content instance of the tag. The search processor 18 renders a visualization (at block 112) of tags grouped together (such as in one word cloud) based on an object grouping criteria, such as one object in the display group, a number of objects, such as a number of objects based on the number of results returned per page.

FIG. 6 illustrates an embodiment of operations performed by the search processor 16 or other component of the content analytics system 2 to generate a visualization of an aggregate display group of tags when the object grouping criteria is a group number of objects to group in one display region (e.g., a word cloud, panel, displayed shape, etc.). An aggregate display group aggregates tags from multiple objects to visualize in a single group. Upon initiating (at block 130) the operation to generate the display group, the search processor 18 determines (at block 132) the group number, such as a maximum number of search results per page. The search processor 18 forms (at block 134) at least one display group instance 70 for the objects having qualifying content instances, wherein each display group instance 70 includes tags 76 for qualifying content instances in groups for up to the determined group number of objects. For each display group instance, the search processor 18 generates (at block 136) a visualization of an aggregate display group (e.g., word cloud) including visualizations of the tags 76 in the objects in the display group instance. At least one of the generated aggregate display groups (clouds) may be included (at block 138) on a search result page 22 to return to the client that originated the search.

In certain embodiments, selection of the visualized aggregate display group instance may provide a link to a search result page providing information on the objects having content instances represented by tags in the visualized display group. In further embodiments, the visualized aggregate display group may not be on the search results page. Instead, there may be a page of visualized aggregate display groups which provide indexes to the search results represented by the visualized aggregate display groups. Alternatively, there may be visualized aggregate display groups on the search results page for the search results in previous and next pages, linked to those pages, to serve as a visual means of determining if the user wants to go to the next (or previous) page. There may be further visualized aggregates of the aggregates to provide further visual abstractions.

FIG. 7 illustrates an embodiment of operations performed by the search processor 18 or other component of the content analytics system 2 to generate display group instances 70 for multiple display group definitions 50 for an object having qualifying content instances satisfying the search criteria. Upon initiating (at block 150) the operation to generate display group instances, the search processor 18 generates (at block 152) a first display group instance 70 from a first display group definition 50, specifying a correlation display attribute 56, including tags based on a correlation attribute value of the qualifying content instances to the search criteria. The tags 76 may have appearance settings 88 based on their correlation value to the search criteria, e.g., content instances having stronger correlation to the search criteria are displayed with a more prominent or different appearance than those content instances having weaker correlation. The search processor 18 applies (at block 154) the appearance settings 88 of the tags 78 in the first display group instance to display the tags in the visualized first display group. The search processor 18 generates (at block 156) a second display group instance 70 from a second display group definition 50 including tags 76 based on a frequency attribute value of the qualifying content instances in the object. The tags for the second display group may have appearance settings based on their frequency value. The appearance settings 88 are applied (at block 158) to the tags 76 in the second display group instance 70 to display the tags in the visualized second display group. The search processor 18 may further generate (at block 160) a third display instance 70 including tags 76 of qualifying content instances 82 based on a difference attribute value indicating an extent to which the qualifying content instance 82 makes the object in which the content is included different from other objects, according to a scope, where scope can be varied between the page, all pages or entire set or collection of objects. The appearance settings 88 are applied (at block 162) to the tags 76 in the third display group instance to display the tags in the visualized third display group instance.

FIG. 8 illustrates an embodiment of operations performed by the object processor 10 and the search processor 18 to generate display groups based on annotations associated with qualifying content instances in the objects 6. Upon initiating the operation to visualize display groups based on annotations, the annotators 14 may perform (at block 182) analytics on the determined objects to determine annotations for the qualifying content instances of the objects. The determination of annotations may be performed with respect to objects having qualifying content instances after determining the qualifying content instances or before receiving the search request, such as during an indexing operation performed with respect to all content in the all the objects 6 in the repository 4. The search processor 18 determines (at block 184) the objects having annotations for each annotation type for which a display group will be generated. For each annotation type for which a display group instance 70 will be generated, the search processor 18 generates (at block 186) tags for the qualifying content instances associated with annotations corresponding to the annotation type to visualize in the display group for that annotation type. The appearance settings of the tags are applied (at block 188) to the tags rendered in the display group for the annotation type to vary the appearance of the tags based on the annotation of the annotation type associated with the qualifying content instance.

FIGS. 9 and 9A through 9I illustrate an example of displaying multiple word clouds in a row for one medical report, comprising the object. FIGS. 9A through 9I provide views of the cloud panels shown in FIG. 9. Multiple rows are displayed to provide word clouds for different reports having content or text satisfying search results. A first word cloud 200 in a row 202 displays dynamic summary of a report (object) based on the query, with search terms highlighted. A second word cloud 204 in the row adjusts appearance based on frequency of the terms satisfying the search results and a third word cloud 206 displays terms based on text analytics for words having a pharmaceutical annotation, indicating words that are pharmaceuticals, with the appearance varying based on the frequency of the pharmaceutical word. A fourth word cloud 208 comprises a timeline of dates mentioned in the report is also displayed for that report. The other two rows display similar word clouds for different medical reports/objects.

Further, word clouds can be generated that aggregate results for multiple objects, so selection of that word cloud displays the word clouds for each of the objects aggregated in the aggregate word cloud. FIGS. 10 and 10A through 10L show aggregate word cloud 230 that aggregates results for multiple of the word clouds for different medical reports 232. FIGS. 10A through 10L provide views of the cloud panels shown in FIG. 10. Selection of aggregate cloud 230 displays a page of results 232 aggregated by the aggregate cloud 230. For instance aggregate cloud 234 aggregates the results for the reasons for visit cloud, such as cloud 236.

Described embodiments provide techniques for generating display groups to provide visualizations of qualifying content instances satisfying a search criteria based on attributes of the qualifying content instances that are used to determine what qualifying content instances appear in the visualization of the display group and the appearance of tags representing the qualifying content instances.
